Short butt is nice for casting if you have the hang of it. Might tale a while to get used to holding the line with your other hand after casting long butt rods like the prevail.

Plenty of reviews online, just dig a bit deeper and you'll find them

 Does that mean that id hold line with left hand?

Any particular reason for that

Also, is the assassin rod a lot better than the prevail

Not knocking the prevail , its ok for tailor / mullys etc , wouldn't consider it a top end rod.

I fish short butt now all the time, suits my style fishing off rocks/beach and it feels more comfortable for me but it takes a while to get used to. No real affect on distance once you get hang of it. I am RH and have LH holding line on spool, rh up the rod . At the end of the day its a matter of preference for everyone and what they feel comfortable with.Mate had short butt and didn't like it.

The assassin will allow you to throw out bigger baits/sinkers , I sold my sons prevail ( I had cut off around 100mm off but section for him as it was too long) but he wanted something stiffer and got him an assassin which he loves ( off Fishwrecked member).

I have one myself as a spare rod.

Have a Purglas I just had made up custom from blank imported from Sth Africa which I use for cliffs and it fought some good fights with Sharks at DHI last month . Also have my trusty old Loomis Franklin Shockwave which has three different tips(5 piece)and that's low mount also.

Low mount rods started coming over here as a lot of Sth Africans use them and I am sure theres a few on this site ( suggest you use search function) and you will be able to get a fair bit of info.

See if you can grab one and have a few casts to see if its to your liking.
